Ferc, the armor looks excellent, a nice show of commitment right there! I'd do a bit of tweaking on the helmet though, just a little bit of sharpness and definition to the white outline around the visor, but otherwise great job.

I'm more of a '3d fabricator' than a '3d modeller', meaning I prefer to construct things from reference, blueprints or schematics rather than to design stuff of my own.
